2005 Subaru Forester Power Steering Fluid — What It Uses and How to Look After It

Yes, power steering fluid is absolutely relevant for the 2005 Subaru Forester. Referencing technical sources, the 2005 Forester Owner’s Manual and the Subaru Factory Service Manual (Steering section) specify a hydraulic power steering system that uses Automatic Transmission Fluid meeting Dexron III specifications as the power steering fluid. Many reservoir caps on this model are also labelled “Use ATF Dexron III.”

For this Forester, the fluid’s job is to transmit hydraulic pressure from the belt-driven pump to the steering rack, giving lighter, smoother steering at parking speeds and confident feel on the open road. Good fluid keeps the pump quiet, the seals healthy, and the steering assistance consistent — whether it’s a run to the shops or a long Kiwi or Aussie road trip.

Servicing-wise, Subaru typically calls for inspection rather than a fixed replacement interval. Workshops across Australia and New Zealand often treat the fluid as a preventative item, refreshing it around 60,000–80,000 km or every 3–4 years, especially if the colour is dark or there’s a burnt smell. Sticking with ATF Dexron III (rather than generic “power steering fluid”) is key for seal compatibility and correct viscosity.

• Check level monthly with the engine warm, keep between the MIN and MAX marks.
• Use only clean, unopened ATF Dexron III when topping up — don’t mix with additives.
• If you hear whining, feel shudder, or see aeration (bubbles) in the reservoir, bleed the system after topping up: turn the wheel lock-to-lock slowly with the engine running, then recheck the level.
• Inspect hoses and clamps for weeping, small leaks quickly turn into big messes and pump damage.

When doing a fluid exchange, a full system bleed helps push out old, moisture-laden fluid and any debris. A simple turkey-baster top swap is okay between proper services, but a professional flush gets the Forester’s steering feeling crisp again. Keeping the correct fluid fresh is a cheap way to extend pump and rack life on this 2005 classic.

Popular questions about 2005 Subaru Forester power steering fluid

What fluid should be used in the 2005 Forester’s power steering?
The 2005 Forester uses ATF meeting Dexron III specifications as its power steering fluid. That’s straight from Subaru’s service literature and typically printed on the reservoir cap. Avoid mixing with generic “power steering fluid” unless it explicitly states Dexron III compatibility.

How often should the power steering fluid be changed?
Subaru generally specifies inspection and top-up rather than a strict change interval. In local workshop practice, a fluid exchange every 60,000–80,000 km or 3–4 years is a sensible preventative step, or earlier if the fluid is dark, smells burnt, or the steering is noisy.

What are signs the fluid needs attention?
Look for heavy steering at low speeds, whining from the pump, shudder when turning lock-to-lock, or foamy fluid in the reservoir. Also check for leaks around hoses and clamps. Any of these symptoms warrant a level check, possible top-up with Dexron III ATF, and a bleed or full flush if needed.
